Abstract

PURPOSE:To enable to form the speaker excellent in the durability and frequency characteristics with increased bonding strength, by the laminated bonding of the cone, coil bobbin and damper at the same time. CONSTITUTION:The tip of the coil bobbin 3 and the inner circumferential edge 4a of the damper are laminated to the circumference 2a of the center through-hole 2 of the conical cone 1, and they are inserted between the metal molds 5 and 6 and pressed. In this case, the thermomolten adhesives is coated or immersed in advance among the three parts 2a, 3a, 4a and the three are bonded unifiedly by the heater 8 provided with the both metal molds 5 and 6. As a result, since the three are surely bonded, the speaker using this diaphragm part has increased durability and frequency characteristics. Further, when the three 2a, 3a, 4a are formed with synthetic resin itself, the unification is made without adhesives.
